Ux500 Device Tree updates for the v5.15 kernel cycle: 

- New device trees for these mobile phones:
   - Samsung Gavini
   - Samsung Codina
   - Samsung Kyle
 - Flag eMMC cards as non-SD non-SDIO to save time
 - Link USB PHY to USB controller in the device tree
 - Fix up the operating points to the actual clock frequencies
